The Yocha Dehe Wintun Nation of California has made a "significant investment" to air a one-minute commercial during Game 3 of the NBA Finals tonight lashing out against the Washington Redskins for its team name, The Washington Post reports.

The commercial, entitled "Proud to Be," lists many names Native Americans are proud to call themselves, among them chief, patriot, mother, soldier, unyielding, struggling, and indomitable. The ad ends: "Native Americans call themselves many things. The one thing they don't" — and immediately cuts to an extended image of a Washington football helmet.

The anti-Redskins ad originally aired online during the Superbowl, but will now broadcast in Chicago, Dallas, Los Angeles, New York, Sacramento, San Francisco, and Washington during tonight's game. It already ran in Miami during the first two games of the Finals.

Although there's been increasing support for the Washington franchise to change its name — most recently 50 U.S. senators sent a letter to commissioner Roger Goodell urging him to do so. The franchise's owner, Daniel Snyder, has vowed to never change the name and calls it "a badge of honor." Goodell has repeatedly claimed the team name is not offensive to Native Americans, citing a decade-old poll.

Two weeks ago, the Redskins took to Twitter in response to Senate Majority Leader Harry Reid voicing his support of the name change.
